I have iphoone 5 on three network in the UK. Unfortunately if I go to poor signal area and phone looses connection it fails to refresh itself when I come out the blackhole.The phone stays non functional until I activate the airplane mode or reboot the phone. It is very dangerous as I rely on the phone in my profession. Looked at the discussions and it seems it is widely known problem with iphone 5. I had replacement phone from apple which did not resolve the issue. It is definitely not a sim problem as I put the sim in iphone 4s and the problem could not be replicated. All the troubleshooting talked about online has been teasted to no avail including the recent ios 6.02 update. Three is aware of issues with iphone 5 and claim the problem is in iphone 5 and they feel a decent update will hopefully resolve the problem.
I just wondered if apple are aware that professionals rely on iphone for communication in mission critical circumstances were lives might be at risk. Is apple happy to announce that iphone 5 should not be used by people who rely on the phone in critical situations ?. Please help..!.
